Embodiments for Carrying Out the Invention

[0012] Hereinafter, one or more embodiments specifically disclosing the device for peeling the bulbous roots of island rakkyo according to the present invention will be described in detail with appropriate reference to the accompanying drawings.

[0013] However, a more detailed description than necessary may be omitted. For example, a detailed description of well-known matters or a redundant description of substantially the same configuration may be omitted. This is to avoid making the following description unnecessarily redundant and to facilitate the understanding of those skilled in the art. Also, each of the accompanying drawings is to be viewed in accordance with the direction of the reference numerals.

[0014] Also, the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and it is not intended to limit the subject matter described in the claims thereby.

[0015] <Explanation of Terms> The terms described hereinafter shall have the meanings defined below.

[0016] The term "comprising (or comprising)" means its standard definition in patent terminology and is an open-ended term that is roughly synonymous with "including", "having" or "containing". "Comprising", "including", "having" and "containing", as well as their variants, are generally used open-ended terms, but the present invention can also be appropriately described using more restrictive terms such as "consisting essentially of". This is a term that conforms to the open-ended term in that it excludes only objects or elements that would have an adverse effect on the performance of the respirator of the present invention when performing its intended function.

[0017] Also, when the phrase "consisting of" is used in this specification, the phrase "consisting of" excludes any element, step or component not specified in the claim. When the phrase "consisting of (or its variant)" appears not immediately after the preamble but rather in the body section of the claim, it limits only the elements shown in that section and does not exclude other elements from the entire claim. The phrase "consisting essentially of" used in this specification limits the scope of the claim to those that do not substantially affect the main components and new features (singular or plural) of the claimed subject matter in addition to the specified elements or method steps.

[0018] Regarding the terms "comprising", "consisting of" and "consisting essentially of", when one of these three terms is used in this specification, the subject matter disclosed and claimed in the present invention may also include the use of any of the other two terms. Therefore, in some embodiments not explicitly stated otherwise, any case of "comprising" can be replaced by "consisting of" or "consisting essentially of".

[0019] The term "process" or "step" may be used explicitly or implicitly in relation to the features of a process or method. However, unless the order or procedure is specified, the order or procedure between such explicit or implicit processes or steps is not limited.

[0020] Hereinafter, each of one or more embodiments of the apparatus for peeling the root part of island rakkyo according to the present invention will be described in detail with reference to the drawings.

[0021] <First Embodiment> A first embodiment of an apparatus 1 (hereinafter also referred to as "apparatus") for peeling the root part KK of island rakkyo OR according to the present invention will be described with reference to FIGS. 1 to 5.

[0022] In the drawings for explaining the present embodiment, among the extending directions (rearward direction: an example of the first direction) of the duct 20 (an example of a working space), the side on which the first injection support portion 40A (an example of the first injection nozzle group) and the second injection support portion 40B (an example of the second injection nozzle group) are disposed is defined as the "front side", and the opposite side is defined as the "rear side". Further, in the duct 20, the direction (an example of the fourth direction) perpendicular (vertical) to both the extending direction and the vertical direction (gravity direction: an example of the second direction, an example of the third direction) is also defined as the "width direction" or the "horizontal direction". In the present embodiment, the second direction and the third direction are set to be the same, but are not limited thereto. The second direction and the third direction may be set to intersect each other.

[0023] [·Regarding the basic configuration of the apparatus] An example of the basic configuration of the apparatus 1 will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view for explaining an example of the configuration of the apparatus 1 for peeling the root part KK of island rakkyo OR according to the present embodiment. FIG. 2 is an enlarged front view of a main part for explaining an example of the structure of the inlet portion of the duct 20 shown in FIG. 1.

[0024] As shown in FIGS. 1 and 2, the apparatus 1 of the present embodiment includes a duct 20 (an example of a work space), support legs 2, a pair of injection support parts 40A and 40B (an example of a first injection nozzle group, an example of a second injection nozzle group), a chamber 3, a pair of sub-pipes 4, a main pipe 5, a storage tank (not shown), and a pressure feeding device (not shown).

[0025] The support legs 2 support the duct 20 so as to maintain a horizontal direction at a predetermined height with respect to the installation surface. Each of the pair of sub-pipes 4 connects (couples) each of the chamber 3 and the injection support parts 40A and 40B and circulates (delivers) water therebetween. The main pipe 5 connects the pressure feeding device and the chamber 3 and delivers water therebetween. An on-off valve VL is provided at each of the pair of sub-pipes 4 and at the base end or the tip end of the main pipe 5. Thereby, the user can open and close the flow path by operating the on-off valve VL.

[0026] The duct 20 is made of a hollow material made of metal (for example, stainless steel) and is formed in a rectangular cross-sectional shape, and is provided to extend in the back-and-forth direction (an example of a first direction) along the horizontal direction, that is, from the front side to the back side in the drawing. The duct 20 is open at both the front side and the back side, and has a straight part 24 and a bent part 30.

[0027] The straight part 24 is disposed in the front side portion. The bent part 30 is disposed in the back side portion. That is, the front side opening 21 of the duct 20 is formed at the front side end of the straight part 24. The back side opening 22 of the duct 20 is formed at the back side end of the bent part 30.

[0028] The straight part 24 has a top wall part 25, a bottom wall part 27, and a pair of side wall parts 28.

[0029] The top wall portion 25 and the bottom wall portion 27 are arranged to face each other in the vertical direction. The pair of side wall portions 28 are arranged to face each other in the width direction of the duct 20 (an example of the fourth direction). In other words, the duct 20 as a working space is partitioned by the top wall portion 25, the bottom wall portion 27, and the pair of side wall portions 28. And in this embodiment, a notch portion 29 is formed at the front end portion of the top wall portion 25 of the straight portion 24. The notch portion 29 is formed in a substantially inverted U shape in plan view, and its tip portion (the back side in the figure) is formed in an arc shape (see FIG. 3).

[0030] The bent portion 30 is connected to the rear end portion of the straight portion 24 and is formed by bending downward in the vertical direction from the back to the front. Therefore, the flow path of the duct 20 is formed in a substantially inverted L shape when viewed from the side direction, and the rear opening portion 22 of the duct 20 opens toward the installation surface.

[0031] The pair of injection support portions 40A and 40B are also made of a hollow metal material, and their radial cross sections are formed in a circular shape. Each of the injection support portions 40A and 40B is erected by connecting the top wall portion 25 and the bottom wall portion 27 in its internal space at the front end portion of the straight portion 24 of the duct 20.

[0032] That is, both the injection support portion 40A on the left side in the figure (hereinafter also referred to as the "first injection support portion") and the injection support portion 40B on the right side in the figure (hereinafter also referred to as the "second injection support portion") are arranged at one end side in the extending direction of the duct 20 (the back-to-front direction: an example of the first direction) and extend along the vertical direction (an example of the second direction, an example of the third direction). Also, each of the first injection support portion 40A and the second injection support portion 40B is disposed at the left end portion (one end portion) or the right end portion (the other end portion) of the duct 20 in the width direction and is arranged to face each other in the width direction.

[0033] That is, in the present embodiment, when the extending direction of the first injection support portion 40A is the second direction and the extending direction of the second injection support portion 40B is the third direction, the second direction and the third direction are directions that follow (an example of "along") the vertical direction and are the same direction. Therefore, the aforementioned first direction (front-rear direction) and the second direction are orthogonal to each other. Similarly, the first direction and the third direction are orthogonal to each other. Also, when the width direction of the duct 20 is the fourth direction, the first direction and the fourth direction are similarly orthogonal to each other.

[0034] Further, each of the first injection support portion 40A and the second injection support portion 40B has its tip end portion (upper end portion) closed and its base end portion (lower end portion) opened, and is connected to the aforementioned sub-pipe 4 at this opening portion (not shown). Water is supplied to each of the first injection support portion 40A and the second injection support portion 40B through each of its openings.

[0035] A plurality of nozzle bodies 41A, 41B (four each in the present embodiment) are arranged along the vertical direction (an example of the second direction, an example of the third direction) in each of the first injection support portion 40A and the second injection support portion 40B.

[0036] That is, the first injection support portion 40A is configured to have a plurality of nozzle bodies 41A and is a first injection nozzle group arranged at the front end portion (an example of one end side in the first direction) of the duct 20. Similarly, the second injection support portion 40B is configured to have a plurality of nozzle bodies 41B different from the first injection support portion 40A (the first injection nozzle group) and is a second injection nozzle group arranged at the front end portion of the duct 20 in the same manner. Therefore, as described above, the first injection nozzle group and the second injection nozzle group are arranged to face each other in the width direction (an example of the fourth direction) of the duct 20.

[0037] Chamber 3 is provided as an intermediate buffer for circulating water, and is fixedly installed on the outer surface of the bottom wall portion 27 at the front end of the duct 20. Chamber 3 is a hollow member formed in a long block shape and extends along the width direction of the duct 20. Chamber 3 temporarily receives the water supplied through the main pipe 5 inside it, and guides and distributes the supplied water to each of the pair of sub-pipes 4.

[0038] The storage tank temporarily stores the water for supplying each of the first injection support portion 40A and the second injection support portion 40B. The pressure pump is arranged adjacent to the storage tank, for example, and is connected to the chamber 3 of the device 1 through (via) the main pipe 5. The pressure pump applies pressure to the water stored in the storage tank and continuously sends (supplies) the water to the chamber 3 through the main pipe 5. As a result, as will be described later, the water is introduced from the chamber 3 through each of the sub-pipes 4 into the first injection support portion 40A or the second injection support portion 40B, and finally discharged to the outside from each of the plurality of nozzle bodies 41A, 41B.

[0039] [Regarding the structures of the first injection support portion and the second injection support portion] With reference to FIGS. 2 and 3, an example of the structures of the first injection support portion 40A and the second injection support portion 40B will be described. FIG. 2 is an enlarged front view of the main part for explaining an example of the structure of the inlet portion of the duct 20 shown in FIG. 1. FIG. 3 is a plan view (top view) for explaining the first state of injection of the first injection support portion 40A and the second injection support portion 40B shown in FIG. 1.

[0040] As shown in FIGS. 2 and 3, each of the plurality of nozzle bodies 41A of the first injection support portion 40A or the plurality of nozzle bodies 41B of the second injection support portion 40B is attached to the rear side and the inner side in the width direction on the circumferential surface of each of the first injection support portion 40A or the second injection support portion 40B. Further, each of the plurality of nozzle bodies 41A and 41B is fixedly arranged in a row at substantially equal intervals along the extending direction of the first injection support portion 40A or the second injection support portion 40B. In this embodiment, the number of each of the plurality of nozzle bodies 41A of the first injection support portion 40A or the plurality of nozzle bodies 41B of the second injection support portion 40B is four, but it is not limited thereto. As long as it is plural, the number is arbitrary.

[0041] In other words, each of the plurality of nozzle bodies 41A of the first injection support portion 40A or the plurality of nozzle bodies 41B of the second injection support portion 40B is arranged in a row at substantially equal intervals in the vertical direction. Further, the plurality of nozzle bodies 41A of the first injection support portion 40A or the plurality of nozzle bodies 41B of the second injection support portion 40B are concentrated and arranged in the middle portion along the extending direction of each of the first injection support portion 40A or the second injection support portion 40B.

[0042] Each of the nozzle bodies 41A of the first injection support portion 40A or the nozzle bodies 41B of the second injection support portion 40B sprays water in a diffused manner so that the spray region (spray pattern) becomes fan-shaped. Specifically, each injection port (not shown) of the plurality of nozzle bodies 41A and 41B is formed in a tapered shape so that the injection shape becomes fan-shaped. Further, each of the injection ports of the nozzle bodies 41A and 41B communicates with the internal space of the first injection support portion 40A or the second injection support portion 40B.

[0043] In this way, when the supplied water is jetted through the respective jet ports of the nozzle bodies 41A and 41B toward the bulbous root KK of the pickled ginger OR, the water comes into contact with and collides with the surface of the bulbous root KK of the pickled ginger OR in a linear form. Therefore, the apparatus 1 can efficiently remove the skin and the soil adhering to the surface at the bulbous root KK thereof.

[0044] Then, the fan-shaped extending directions of the nozzle bodies 41A of the first jet support part 40A are set to be substantially coincident (aligned) with each other. Further, the extending direction thereof is along the vertical direction (an example of the second direction), and is set to be inclined toward the back side of the duct 20 (an example of the other end side of the first direction) and the side closer to the second jet support part 40B.

[0045] That is, each of the plurality of nozzle bodies 41A of the first jet support part 40A has a fan-shaped spray pattern, and the perpendicular of the shape is set in a direction substantially along the horizontal direction. Then, each of the plurality of nozzle bodies 41A of the first jet support part 40A is inclined so as to face both the back side of the duct 20 and the other end side in the width direction of the duct 20 (the right end side in the figure) in a plan view (top view), and sprays water while diffusing it in a fan shape.

[0046] Similarly, the fan-shaped extending directions of the plurality of nozzle bodies 41B of the second jet support part 40B are set to be substantially coincident with each other. Further, the extending direction thereof is along the vertical direction (an example of the third direction), and is set to be inclined toward the back side of the duct 20 and the side closer to the first jet support part 40A.

[0047] That is, similarly, each of the plurality of nozzle bodies 41B of the second jet support part 40B has a fan-shaped spray pattern, and the perpendicular of the shape is set in a direction substantially along the horizontal direction. Then, each of the plurality of nozzle bodies 41B of the second jet support part 40B is inclined so as to face both the back side of the duct 20 and one end side in the width direction of the duct 20 (the left end side in the figure) in a plan view (top view), and sprays water while diffusing it in a fan shape.

[0048] In this way, the water jetted from each of the plurality of nozzle bodies 41A of the first jet support portion 40A and the water jetted from each of the plurality of nozzle bodies 41B of the second jet support portion 40B collide closer to the back side (the other end side in the first direction) of the duct 20 than the arrangement positions of the first jet support portion 40A and the second jet support portion 40B. And the collision portion 42 extends along the vertical direction and is arranged (located) in the middle in the width direction of the duct 20, in other words, in the middle of the first jet support portion 40A and the second jet support portion 40B when viewed from the front (an example of "when viewed according to the first direction").

[0049] Also, in the present embodiment, in a plan view (top view), the crossing angle A0 between the jetting directions from the plurality of nozzle bodies 41A of the first jet support portion 40A and the jetting directions from the plurality of nozzle bodies 41B of the second jet support portion 40B is set to an obtuse angle. The crossing angle A0 is preferably set in the range where the angle is from 120 degrees to 150 degrees.

[0050] Also, in the region of the duct 20 on the back side of the collision portion 42, the water after the collision is diffusely spread in a wide range in a mist shape over the entire portion sandwiched by the jetting directions of the first jet support portion 40A and the second jet support portion 40B due to the impact. Therefore, when the user uses the device 1 to perform the peeling work of the mountain yam OR, it is advisable to first place the root portion KK of the mountain yam OR in the diffusion region and then pull and move it. In this case, it is possible to moderately moisten the mud adhering to the surface of the root portion KK without applying excessive impact thereto and then make it easy to remove.

[0051] Note that at the front end of the top wall of the duct 20, between each of the notch portion 29 and the pair of side wall portions 28, a pair of elongated holes 23 extending in the width direction of the duct 20 are formed. Bolts BT are inserted into each of the elongated holes 23 and fastened to the tip of the first injection support portion 40A or the second injection support portion 40B. By this fastening, the first injection support portion 40A or the second injection support portion 40B is fixed to the duct 20. Further, the user appropriately changes the insertion position of the bolt BT in each of the elongated holes 23 along the extending direction of the elongated holes 23. Thereby, the user can arbitrarily adjust both the separation distance between the first injection support portion 40A and the second injection support portion 40B and the injection angle thereof.

[0052] [Regarding the configuration of the inner wall of the duct] An example of the internal configuration of the duct 20 will be described with reference to FIG. 4. FIG. 4 is a plan sectional view for explaining an example of the internal structure of the duct 20 shown in FIG. 1.

[0053] As shown in FIG. 4, a pair of inner wall members 50 are attached (arranged) to the inner surfaces of the pair of side walls of the duct 20. The pair of inner wall members 50 are arranged to face each other in the width direction of the duct 20. Each of the pair of inner wall members 50 is formed to extend in the back-and-forth direction of the duct 20 and is formed by, for example, press-working a plate-like member.

[0054] Each of the pair of inner wall members 50 integrally includes a pair of attachment piece portions 51, a first inclined surface portion 52 (an example of a first inclined surface), a flat surface portion 53 (an example of a flat surface), and a second inclined surface portion 54 (an example of a second inclined surface).

[0055] The pair of attachment piece portions 51 are formed in a long plate shape and extend in the vertical direction. The pair of attachment piece portions 51 are disposed at the front ends of the inner wall members 50 in the back-and-forth direction and are fixed to the inner surface of the side wall portion 28 of the duct 20 by, for example, fastening members or welding. By this fixing, each of the inner wall members 50 is fixed to the internal space of the duct 20.

[0056] The first inclined surface portion 52 is connected to the inner end portion of the mounting piece portion 51 located on the front side of the duct 20. In the pair of inner wall members 50, the respective first inclined surface portions 52 are arranged to face each other in the width direction of the duct 20, and are inclined so as to approach each other as going deeper into the duct 20.

[0057] The second inclined surface portion 54 is arranged deeper inside the duct 20 than the arrangement position of the first inclined surface portion 52, and is connected to the front end portion of the mounting piece portion 51 located inside the duct 20. In the pair of inner wall members 50, the respective second inclined surface portions 54 are arranged to face each other in the width direction of the duct 20, and are inclined so as to separate from each other as going deeper into the duct 20. Further, in the present embodiment, the inclination angle A2 of the second inclined surface portion 54 is set smaller than the inclination angle A1 of the first inclined surface portion 52.

[0058] [·Regarding the usage method of the device] With reference to FIG. 5, an example of the usage method of the device 1 will be described. FIG. 5 is a plan view (top view) for explaining the second state of the injection of the first injection support portion 40A and the second injection support portion 40B shown in FIG. 1.

[0059] First, before using the device 1, the user (operator) arranges a plurality of island ginger ORs so that the bulbous roots KK face the same direction, and then prepares them in bundles.

[0060] Then, the operator grips the plurality of island ginger ORs in bundles so that the bulbous roots KK of the island ginger ORs face the inner side of the duct 20, and positions them above the notch portion 29 of the duct 20. Next, the operator lowers the bundle so as to pass through the notch portion 29 of the duct 20 while maintaining the gripping state.

[0061] At this time, when gripping the plurality of island ginger ORs in bundles, the user may grip by pinching the leaf portion or the portion between the leaf portion and the bulbous root KK. In this case, it is possible to improve the gripping workability.

[0062] As shown in Fig. 5, when lowering, the operator inserts the bundle into the inside of the duct 20 in a state along the horizontal direction. At this time, the operator initially sets the bulbous root KK of the island Chinese chive OR to be located deeper inside the duct 20 than the collision part 42 of the jet water, and the leaf part or the part between the leaf part and the bulbous root KK is located at the collision part 42 of the jet water.

[0063] From the state of the initial setting, the operator pulls and moves the bundle of the island Chinese chive OR toward the front side, that is, the side of the operator's body. By this movement, at the collision part 42 of the jet water, the part of the island Chinese chive OR that is hit by water moves from the leaf part or the part between the leaf part and the bulbous root KK to the bulbous root KK. In the process of this movement, the skin of the bulbous root KK of the island Chinese chive OR is efficiently removed.

[0064] By using the apparatus 1 in this way, it is possible to realize peeling of the bulbous roots KK of the island Chinese chive OR in large quantities and smoothly, and to improve the working efficiency of peeling the island Chinese chive OR.

[0065] [Regarding the features and advantages of this embodiment] As described above, according to the peeling device 1 for the bulb base KK of the island rakkyo OR of the present embodiment, there is a duct 20 (an example of a working space) extending along the back direction (an example of the first direction) extending horizontally, and a plurality of nozzle bodies 41A are configured, and a first injection support portion 40A (an example of a first injection nozzle group) disposed on one end side in the back direction of the duct 20, and a plurality of nozzle bodies 41B different from the first injection support portion 40A are configured, and a second injection support portion 40B (an example of a second injection nozzle group) disposed on one end side in the back direction of the duct 20. Further, the first injection support portion 40A and the second injection support portion 40B are disposed to face each other in the width direction of the duct 20 (an example of the fourth direction) that intersects the back direction and extends horizontally. Further, each of the plurality of nozzle bodies 41A of the first injection support portion 40A is arranged to be spaced apart from each other along the vertical direction (an example of the "second direction that intersects the first direction and extends along the vertical direction"). Further, each of the plurality of nozzle bodies 41B of the second injection support portion 40B is arranged to be spaced apart from each other along the vertical direction (an example of the "third direction that intersects the first direction and extends along the vertical direction"). Further, each of the plurality of nozzle bodies 41A of the first injection support portion 40A is supplied with water (an example of a liquid) and injects the water in a fan shape, and the extending direction of the fan shape is along the vertical direction and is inclined toward the back side (an example of the other end side) in the back direction of the duct 20 and closer to the second injection support portion 40B side. Further, each of the plurality of nozzle bodies 41B of the second injection support portion 40B is supplied with water (an example of a liquid) and injects the water in a fan shape, and the extending direction of the fan shape is along the vertical direction and is inclined toward the back side in the back direction of the duct 20 and closer to the first injection support portion 40A side. Further, the water injected from each of the plurality of nozzle bodies 41A of the first injection support portion 40A and the water injected from each of the plurality of nozzle bodies 41B of the second injection support portion 40B are set to collide closer to the back side in the back direction of the duct 20 than the arrangement positions of the first injection support portion 40A and the second injection support portion 40B.

[0066] Therefore, the user (operator) bundles multiple rakkyo ORs, holds them on the leaf side, and positions the bulbous roots KK on the other end side (the back side) of the duct 20 (an example of a working space). In this state, the user arranges the multiple bulbous roots KK between the first injection support portion 40A (an example of the first injection nozzle group) and the second injection support portion 40B (an example of the second injection nozzle group) on the back side of the duct 20 with reference to the water (an example of a liquid) collision portion 42. Then, the user pulls and moves the bundled multiple rakkyo ORs together to the front side (an example of one end side) of the duct 20, and the bulbous roots KK pass through the collision portion 42. By this passage, a large amount of the skin of the bulbous roots KK of the rakkyo OR can be peeled off (removed) smoothly. As a result, a large amount of the skin peeling of the bulbous roots KK of the rakkyo OR can be realized smoothly, and the working efficiency can be improved.

[0067] Further, according to the skin peeling device 1 for the bulbous roots KK of the rakkyo OR of the present embodiment, the back-and-forth direction (an example of the first direction) and the extending direction of the first injection support portion 40A (an example of the second direction) are set to be orthogonal to each other. Also, the back-and-forth direction and the second injection support portion 40B (an example of the third direction) are set to be orthogonal to each other. Further, the back-and-forth direction and the facing direction of the first injection support portion 40A and the second injection support portion 40B (an example of the fourth direction) are set to be orthogonal to each other.

[0068] For this reason, the skin of the bulbous roots KK of the rakkyo OR can be peeled off more reliably using the device 1.

[0069] Further, according to the skin peeling device 1 for the bulbous roots KK of the rakkyo OR of the present embodiment, the collision portion 42 where the water (an example of a liquid) ejected from the first injection support portion 40A (an example of the first injection nozzle group) collides with the water (an example of a liquid) ejected from the second injection support portion 40B (an example of the second injection nozzle group) extends along the vertical direction and is arranged in the middle of the first injection support portion 40A and the second injection support portion 40B when viewed in accordance with the back-and-forth direction (an example of the first direction) of the duct 20.

[0070] Therefore, the skin of the bulbous base KK of the orchid rakkyo can be peeled off more easily and surely using the apparatus 1.

[0071] Further, according to the skin peeling apparatus 1 for the bulbous base KK of the orchid rakkyo of the present embodiment, a duct 20 (an example of a working space) is defined by a top wall portion 25 (an example of a top wall) and a bottom wall portion 27 (an example of a bottom wall) that are disposed opposite to each other in the vertical direction. Further, in the top wall portion 25, a notch portion 29 is formed on the front side (an example of one end portion) in the back direction (an example of the first direction) of the duct 20.

[0072] For this reason, since the notch portion 29 is formed in the top wall portion 25 (an example of a top wall), the user lowers a plurality of orchid rakkyos OR from above the duct 20 (an example of a working space) with the plurality of orchid rakkyos OR bundled together and passes them through the notch portion 29. By this passage, the bulbous base KK is directly disposed on the back side (an example of the other end side) of the duct 20 with reference to the collision portion 42 of water (an example of a liquid). In that arranged state, the user pulls and moves the plurality of orchid rakkyos OR together in a bundle. Thereby, the work efficiency of the user is increased, and as a result, a large amount of skin peeling processing can be easily realized.

[0073] Further, according to the skin peeling apparatus 1 for the bulbous base KK of the orchid rakkyo of the present embodiment, the duct 20 (an example of a working space) is defined by a pair of side wall portions 28 (an example of side walls) that are disposed opposite to each other in the width direction (an example of the fourth direction) of the duct 20. Further, on each of the inner surfaces of the pair of side wall portions 28 (an example of side walls), first inclined surface portions 52 (an example of a first inclined surface) that face each other in the width direction of the duct 20 are disposed. Further, each of the first inclined surface portions 52 is inclined so as to come closer to each other as going toward the back side (an example of the other end side) in the back direction (an example of the first direction) of the duct 20.

[0074] For this reason, due to the presence of the first inclined surface portions 52 (an example of a first inclined surface), the peeled skin is aggregated and flown and moved toward the back side (an example of the other end side) of the duct 20 (an example of a working space). Thereby, the collection of the peeled skin can be facilitated and the work efficiency can be increased.

[0075] Further, according to the peeling device 1 for the bulbous part KK of the island rakkyo OR of the present embodiment, on each of the inner surfaces of the pair of side wall portions 28 (an example of a side wall), a second inclined surface portion 54 (an example of a second inclined surface) is disposed on the back side (an example of the other end side) in the back direction (an example of the first direction) of the duct 20 from the disposed position of the first inclined surface portion 52 (an example of the first inclined surface), and the second inclined surface portions 54 face each other in the width direction (an example of the fourth direction) of the duct 20. Further, each of the second inclined surface portions 54 is inclined so as to move away from each other as it goes to the back side in the back direction of the duct 20.

[0076] Therefore, due to the presence of the second inclined surface portion 54 (an example of the second inclined surface) in addition to the first inclined surface portion 52 (an example of the first inclined surface), the recovery of the peeled skin can be made easier and the working efficiency can be further improved.

[0077] Further, according to the peeling device 1 for the bulbous part KK of the island rakkyo OR of the present embodiment, the inclination angle A2 of the second inclined surface portion 54 (an example of the second inclined surface) is smaller than the inclination angle A1 of the first inclined surface portion 52 (an example of the first inclined surface).

[0078] Therefore, the recovery of the peeled skin can be made even easier and the working efficiency can be further improved.

[0079] Further, according to the peeling device 1 for the bulbous part KK of the island rakkyo OR of the present embodiment, on each of the pair of side wall portions 28 (an example of a side wall), a flat surface portion 53 (an example of a flat surface) is disposed between the first inclined surface portion 52 (an example of the first inclined surface) and the second inclined surface portion 54 (an example of the second inclined surface), and connects the back side (an example of the other end portion) in the back direction (an example of the first direction) of the duct 20 of the first inclined surface portion 52 and the front side (an example of one end portion) in the back direction of the duct 20 of the second inclined surface portion 54.

[0080] Therefore, in addition to the first inclined surface portion 52 (an example of the first inclined surface) and the second inclined surface portion 54 (an example of the second inclined surface), the presence of the flat surface portion 53 (an example of the flat surface) can further facilitate the recovery of the peeled skin.

[0081] [·First Modification Example of the Present Embodiment] If a work space can be set (secured), a structure such as the duct 20 may not be provided. Alternatively, instead of the duct 20, a work space defined only by a pair of opposing side wall portions 28, 28 in the horizontal direction, or a work space defined only by the top wall portion 25 and the bottom wall portion 27 opposing in the vertical direction may be used. Even in this case, the same operational effects as those of the present embodiment are achieved.

[0082] [Finally] With the above, the description of the specific embodiments is completed. However, the aspects of the present invention are not limited to these embodiments, and can be appropriately modified, improved, etc. [Industrial Applicability]
